You can write your own version of grep in python using os.walk, open, read and find. I don't know why one would want to do that unless for portability reasons. It will be pretty hard to beat grep in efficiency and succinctness. The most sensible thing IMHO is a shell script or call grep using os.system (or using subprocess). -- http://mail.python.org/mailman/listinfo/python-list
